Quick Summary
- 1Core ERP (Finance + Inventory + Sales + Purchase): $40K–$120K, 14–22 weeks
- 2Manufacturing or multi-warehouse adds $25K–$80K
- 3Custom ERP often cheaper TCO than SAP/Oracle over 5 years for SMEs
- 4GST e-invoice + e-way bill must be built in, not bolted on
SAP S/4HANA and Oracle NetSuite are excellent — and overkill for 80% of Indian mid-market businesses. A well-built custom ERP, designed around the way your business actually runs, often costs less to own over 5 years than a licensed suite, fits your workflows precisely, and integrates cleanly with the dozen smaller tools your team already loves. Here is the 2026 reality of custom ERP development in India.
When custom ERP makes sense
- Your industry has workflows that no standard ERP models well (jewellery, textiles, agri, AYUSH, marine, custom job-shop manufacturing).
- You have outgrown Tally / Zoho / QuickBooks but are not yet large enough to justify SAP.
- You need tight integration with marketplaces, payment gateways, logistics, or government portals (e-invoice, e-way bill, ICEGATE).
- You want to own the source code, the data, and the roadmap.
Module-by-module pricing (2026)
- Finance + accounting + GST: $15K–$35K — chart of accounts, journals, AR/AP, GST returns (GSTR-1/3B), e-invoice via IRP, TDS, bank reconciliation.
- Inventory + warehouse: $10K–$25K — multi-location stock, batch/serial tracking, barcode scanning, stock transfers, e-way bills.
- Sales + CRM: $8K–$20K — leads, quotations, sales orders, dispatch, invoicing.
- Purchase: $6K–$15K — vendor management, RFQ, PO, GRN, vendor payments.
- Manufacturing: $25K–$80K — BOM, routing, work orders, shop floor data capture, MRP, quality control.
- HR + payroll: $10K–$25K — PF, ESI, professional tax, payroll, attendance integration.
- Multi-entity / multi-warehouse: $20K–$60K — inter-company transactions, consolidated reporting.

Planning a Website? Don't Overpay or Underbuild
Most businesses overspend on features they don't need — or underspend and rebuild within a year. We help you scope it right from day one.
Typical timeline
Discovery and BRD: 3–4 weeks. Core ERP (Finance + Inventory + Sales + Purchase): 14–22 weeks. Manufacturing add-on: another 10–14 weeks. Pilot with one branch, then phased rollout — never big-bang go-live. Plan 8–12 weeks of hypercare after each major rollout.
The integrations that always appear
- Tally migration (one-time, historical data)
- GST IRP and e-way bill APIs
- Payment gateways (Razorpay, Cashfree, PayU)
- Logistics (Delhivery, Shiprocket, Bluedart)
- Marketplaces (Amazon, Flipkart, Meesho) for D2C/B2B sellers
- Bank statement parsers for auto-reconciliation
- WhatsApp Business API for invoice and dispatch notifications
Build vs buy: the honest 5-year TCO comparison
Zoho One: predictable monthly fees but customisation ceilings hit fast. SAP B1 / NetSuite: $60K–$150K licence + $40K–$120K implementation + $20K+/year ongoing. Custom ERP: $80K–$200K build + $15K–$40K/year support. Over 5 years, a custom ERP for a 50–200 user company typically lands 20–40% lower TCO — and you own everything.

Red flags when picking a vendor
- "We have a ready-made ERP, we will just rebrand it for you." That is a license, not custom.
- No BRD, no wireframes — straight to coding.
- No GST e-invoice and e-way bill in the demo.
- No multi-environment setup (dev / staging / UAT / prod).
- No documented data migration plan from Tally / Busy / existing system.
